3- i l1 q-?e 5e' a i a To all who m it may concern Be it known that I,Moses Ewme, a citizen of the United States, residing at Chester, in thecounty of Delaware and State of Pennsylvania, have invented certain newand useful Improvements in Slab-Catcher Stop-Motions for Winders, ofwhich the following is a specification.

My invention relates to improvements in slub-catcher stop motion forwinders, and more particularly to an improved sluh catching attachmentfor cone winders, the object of the invention being to provide aneliicient slub catcher which will clear the thread, preventing lumps orslulos from passing to the cone and causing the thread to break beforepermittinga slub or lump to pass.

A further. object is to provide a slub catcher comprising two brushessupported at the ends of lazy tongs which are supported in such a mannerthat when the thread. breaks, the brushes will separate and the cone beelevated out of contact with its friction driving roll.

This is a division of my application for patent on improvements in slubcatchers, filed April 1, 1913, and given Serial No. 758,165.

\Vith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out tn theclaims.

In the accompanying drawings: Figure 1 is a view partly in sectionandpartly in side elevation illustrating my improvements in normaloperative position. Fig. 2 is a plan view of the slab catcher 7961' se.Fig.3 is a view similar to Fig.1 showing the position of the parts whenthe thread breaks. Fig. 4 is a perspective view of one of the brushes.Fig. is a view in cross section on the line 5-5 of Fig. 2. Fig. 6 is aview in front elevation with the parts as shown in 1, and Fig. 7 is aperspective view the wire frame supporting bracket.

My improvements are used in connection with a cone winding machine, andI have illustrated in connection with niy improvements, only suchportions of the machine as are necessary to illustrate the carrying outof my invention.

. is a horizontal bar constitntinga fixed or stationary part of themachine frame having brackets 2 secured thereon and sup porting a shaft3 containing a roll t which is adapted to frictionally turn a cone 5when the latter rests thereon. This cone 5 is supported by a rotaryholder {i secured to, one member 7 ofa'oelLerank-1ever8 which ispivot-ally supported on a rod 9 mounted in extensions 10 onbrackets 2. X

TllGbl'tICkOtS 2 are madewith bearings 11 to receivearbors 12 secured insleeves 12-3 on a plate 15L, and afford pivotal ounting for this plate.Plate leis made with posts 15 at its upper end in \vhieh a wire guide 16is securedand overthis gnide 16, the thread to he wound on the cone ispassed, and is directed onto the cone by "a uide 17 mounted to slide ona bar 18 and operated by a cam 19, fragment of the latter beingillustrated. i I

Q h OWer end of plate 14, a relatively long arm 20 and a relativelyshort arm 21 are cast integral with the plate and support arod 22. i i AA catch 23 is pivotally supported bGtWfiQll its ends on the rod '22, andis normally held in an elevated positionloy a wire frame 24 whichsupported in abracket 25 secured to the plate 14}. This wire frarne 24at one end has a crank arm 26 whic 1 hears against the shorter endiff?of catch 23, while the opposite end of his wine franc constitutesallQIflZ/aQllhlll" guide 28 under whichtlw COrd 17 is positionedandmaintained elevated by th o so as. h sa b e s, h frame 23 will fall andpermit the eateh 23 to fall to the position shown in dotted lines inFig, 1 into tie path o movement of an oscillating trip; 29, continuouslyoscillating with n :shatt When the catch falls to t is .p tim thedownward s il at ng o m QT he out 29 w um the pla dpwnwardly upon itsarhors 12 to the positioi rshown in 3.

. 'l heplate in its normal operative Po i e by Series il se r r b e d haing u ved reces 32 in it e en which receives a rotary sleeve 33,011 apin 34; fired in intcgralears on thebotton of pla 1t When h We s m l s dn 1- wardly by the oscillator 39, the sleeve 3 will be drawn rearwardlyout of the recess and l e i he poetic h n 1. F s- 3 i When againelevated, the recessed end 32 will spring upwardly and hold the parts innormal position as will be readily understood.

A frame 36 is pivotally mounted on the rod 22, and is formed at one endwith a finger hold 37. This frame when moved upwardly by the finger hold37 will engage the shorter end of catch 23, hold the same in elevatedposition, and allow the plate 14 to be raised to operative positionwithout stopping the oscillator 29. In other words, this upward movementof the plate by means of the frame 36, first swings the catch 23 out ofthe path of the oscillator 29, and when the plate is elevated and thecord in operative position with relation to the wire frame 24, the catchwill be held in this position.

A toothed bar 38 is connected to hellcrank-lever 8, and extends througha slot 39 in a bracket 40 on one of the posts 15. The teeth of this bar38 engage the lower wall of the slot 39, so that when the plate 14falls, bar 38 will be drawn forwardly and elevate the cone 5 out ofengagement with roll 4, thereby stopping the turning of the cone. Theteeth of bar 38 are inclined or ratchet shaped, so that as the coneincreases in diameter, this bar may be moved rearwardly tooth by toothso that the cone will be elevated regardless of its diameter in theevent the thread breaks.

The relatively long arm 20 supports at its free end a short rod 41 onwhich a table 42 is secured. This table 42 at its outer edge has a guide43 through whichthe cord 17 is drawn, and on the table a rotary weight44 is mounted on a vertical post 45 and bears upon the cord to act as atension device. Between the table 42 and the wire frame 24, the cordpasses through my improved slub catcher, which consists of two brushes46 facing each other and supported in holders 47 fixed to the ends of alazy tongs 48. This lazy tongs 48 comprises four links as clearly shownin Fig. 2 pivotally connected as shown, and one pivotal connection atthe lower end of the lazy tongs consists of a bent rod 49 which isrigidly secured to the frame bar 1, and acts as a stationary pivot forthe lazy tongs. The upper pivot 48 of the lazy tongs comprises a screwwhich is secured to arm 25 on bracket 25, so that when the plate 14moves downwardly, the lazy tongs operates to separate the brushes asclearly shown. The brushes each consist of a backing plate 50 preferablyof fabric through which a large number of wires 51 project, forming anextended wire surface. The backing plates 50 are adapted to be slid intoand out of the holders 47, so that the brushes may be readily replacedwhen worn or broken.

When the plate 14 is elevated to operative position,

the lazy tongs 48 will bring the brushes together, engaging the thread17 with the teeth of the brushes located side by side, that is, theteeth of one brush will project between the teeth of the other brush,and form a circuitous passage for the thread and insure the catching ofany slub or lump of the thread. In other words, the brushes absolutelyinsure a clean smooth thread to the cone, and if the slub, lump, or knotis so fixed to the thread that it will not pass through the brushes, thethread will be broken and the parts moved downwardly as above explained,elevating the cone 5 and stopping the operation of Winding until thethread is repaired, and the parts moved back into normal position. Itwill thus be seen that with my improved slub catcher, the dropping ofthe plate of the frame due to the breaking of the ,cord, will cause thebrushes to separate and when the parts are moved back to normalposition, the brushes will come together on opposite sides of the cord,so that the operation of the slub catcher is automatic with theoperation of the other parts of the apparatus.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is:

1. The combination with a roll, and a winding mechanism above the rolland turned thereby, of a pivoted plate, means for elevating the windingmechanism out of contact with the roll when the plate falls to its lowerposition, a spring normally holding said plate in elevated operativeposition, means for drawing the plate downwardly into inoperativeposition, a catch operated by said means, a wire frame on the platenormally holding the catch out of engagement with the said means, saidwire frame held in operative position by the thread to be wound, a slubcatcher. comprising two brushes engaging the thread in advance of thewire frame, and a support for said brushes compelling the brushes toseparate when the plate moves clownwardly, substantially as described.
